I prefer wild and sloppy solos to note-perfect guitar masturbation.
J. Mascis of Dinosaur Jr. can solo like a wild motherf
ucker. His solo at the end of 'Freak Scene' is a firm favourite of mine.
Kurt's solo in 'Heart-Shaped Box' by Nirvana is probably the ultimate anti-solo. Sounds like he's strangling his guitar.
The perfect antithesis to self-indulgent guitar solos is Evan Dando's epic one-note solo in 'Great Big No'. 'Stairway to Heaven' my ass.
